Mapping System-Assisted Bipolar Radiofrequency Ablation for the Treatment of Ventricular Tachycardia Associated With Ventricular Aneurysm.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe management of malignant ventricular tachycardia (VT) in the aftermath of a myocardial infarction is a complex undertaking, particularly in cases accompanied by left ventricular aneurysm (LVA). It is frequently the case that conventional unipolar radiofrequency catheter ablation (RFCA) is inadequate. CASE SUMMARY: A 50-year-old male patient with a medical history of myocardial infarction presented with recurrent VT due to a LVA. Initial unipolar RFCA proved to be an ineffective treatment. Bipolar RFCA guided by CARTO mapping during coronary artery bypass grafting has been demonstrated to successfully ablate the LVA. Subsequent postoperative follow-up revealed no recurrence of VT and sustained cardiac function over a 2-year period. DISCUSSION: Refractory VT due to LVA poses significant treatment challenges. Bipolar RFCA, guided by CARTO mapping, has been shown to offer an effective solution, overcoming the limitations of unipolar RFCA by targeting both epicardial and endocardial arrhythmogenic substrates. This case demonstrates a surgical approach with the potential to yield favorable outcomes.
